In 1829, John Walker, an English chemist, ____ created the ____ when experimenting with ways to make fire ____. A ____ of wood, soaked in a ____ mixture he was testing, caught fire through ____ when it dropped near the fireplace. While Walker sold his matches in boxes of 50, he never ____ his ____ and only sold 168 ____, at one shilling each. Two years later, Isaac Holden ____ invented a similar thing, but again ____ to patent the ____. That's where one Samuel Jones came in. Jones, ____ that Walker and Holden had ____ created one of the most useful inventions in the ____ of civilization, decided to make money off it himself, because he was nice like that. Almost immediately, Jones patented the exact same thing and began ____ it under the name "____," because if you're gonna be ____, you might as well go for it. Soon other ____ began offering their own ____ versions, all for a price, of course. While Jones's matches were eventually ____, he made huge profits from the patent. It wasn't until they were all dead that John Walker was finally ____ for his invention. It's sad that the ____ inventors saw such little ____ from a business that now sells a billion matches a year in the US alone!
